I try to reconstruct the first animations using the pot to control the speed (frames/sec) and the motor to control the motion
Parts:
DC motor
Arduino
POT
diode
transistor
CODE
/*
* one pot fades one motor
* modified version of AnalogInput
* by DojoDave <http://www.0j0.org>
* http://www.arduino.cc/en/Tutorial/AnalogInput
* Modified again by dave Modified to control the speed
*/
int potPin = 0; // select the input pin for the potentiometer
int motorPin = 9; // select the pin for the Motor
int newval = 0;
int val = 0;// variable to store the value coming from the sensor
void setup() {
Serial.begin(9600);
}
void loop() {
val = analogRead(potPin); // read the value from the sensor, between 0 - 1024
newval = map (val, 0, 1024, 0, 60);
Serial.println(val);
analogWrite(motorPin, newval); // analogWrite can be between 0-255
}
